Multi-Tenant Architecture
Built from the ground up for multi-tenant SaaS delivery.
BizBrew's architecture is designed for multi-tenant operation from the ground up. Each tenant gets isolated data, independent configuration, and their own subdomain — all running on shared infrastructure for efficiency. Row-level security at the database level, tenant-scoped API routes, and a sophisticated entitlements system ensure that every request is properly authorised and scoped.
What's included
Tenant isolation
Every tenant's data is isolated via PostgreSQL RLS policies.
Per-tenant configuration
Each tenant has independent modules, settings, and branding.
Subdomain routing
Automatic subdomain provisioning (tenant.bizbrew.org) for every business.
Entitlements system
Module access controlled by subscription plan and tenant settings.
Tenant-scoped APIs
Every API route enforces tenant context via middleware headers.
Horizontal scalability
Shared infrastructure scales across tenants without per-tenant overhead.
Frequently asked questions
What is multi-tenant architecture?
Multi-tenant means multiple businesses share the same application infrastructure but each has completely isolated data and configuration. This keeps costs low while maintaining security and privacy.
Is my data safe from other tenants?
Yes. PostgreSQL Row-Level Security (RLS) policies enforce data isolation at the database level. Every query is automatically scoped to your tenant — other tenants cannot access your data.
Can I have different modules enabled than other businesses?
Absolutely. Each tenant can have a different set of modules enabled based on their subscription plan and business type. The entitlements system manages this automatically.
